But got bitten by std::vector<bool> as it is specialized and uses bitsets (i.e. integers) internally.
Less memory but at the cost of 'oh, sorry std::vector<bool> does not return a bool&'.
That again seems to be a problem for the SparseMatrix<bool> instatiation since for instance getValue returns a T&.
On the one hand I don't quite know why this was never an issue before and on the other hand it prevents successful compilation.
So there are different ways to settle this:
- Specialize SparseMatix for bool -> possibly lots of code, but might be the best solution
- Write a wrapper for std::vector that uses chars instead of booleans
- Dont't use SparseMatrix<bool>
Next up: Figure out the best solution for this and implement it.
